SASH-BALANCE.

SPECIFICATION forming part of Letters Patent No. 416,207, dated December3, 1889.

Application filed September 15 3, 1889. Serial No. 324,312. (No model.))

To all whom it may concern:

Be it known that I, JACOB BAsTIAN, of Dansville, in the county ofLivingston and State of New York, have invented certain new and usefulImprovements in Sash-Holders; and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming a part of this specification, andto the letters of reference marked thereon.

My present invention relates particularly to that class of sash-holdersadapted to prevent the sudden descent of the sash and to hold the sameat any desired point, but which will permit it to be moved freely in anupward direction, the object of the invention being to produce asuperior and cheap device for accomplishing the desired end which shallbe noiseless and composed of few and simple parts.

The invention therefore consists in certain novel details ofconstruction and combinations and arrangements of parts, to behereinafter described, and pointed out particularly in the claims at theend of this specification.

In the accompanying drawings, Figure 1 is a perspective View of a holderconstructed in accordance with my invention, a portion --of the framebeing broken away and the sash and easing shown in dotted lines. Fig. 2is a Vertical section. Fig. 3 is a side elevation with the side of theframe removed. Fig. 4 is a section at right angles to Fig. 2.

Similar letters of reference in the several figures indicate the sameparts.

The frame A, in which the working parts of my invention are mounted, maybe of any desired construction, although preferably constructed, asshown, with the back open and with an opening in the front plate for thepassage of the supporting'strap, and through which the brake may betightened, as will hereinafter appear. The sides of the frame are ofcourse suitably braced and bound together with rivets and pillars orbolts, and journaled in said sides is the shaft or axle B, to which isrigidly secured the friction-drum O and ratchet-Wheel D. The drum B ispreferably of wood, and is securely fastened, by rivets or otherwise, toa plate or disk E, formed integral with the ratchet-wheel and axle. Atone side of and partially surrounding the ratchet-Wheel and drum isjournaled the winding drum, consisting of the grooved wheel F, adaptedfor the reception of the supporting-tape G, and the annular extension H,surrounding the shaft, and to which is attached the inner end of theretracting-spring I, the opposite end of said spring being attached tothe bolt 1' on the frame. IVithin the grooved wheel, and in position toengage the ratchet-wheel, are located four spring-pressed pins K, whichconstitute pawls and serve to lock the drum and wheel together whenrotated in one direction, but permit of the free rotation of the wheelin the opposite direction. The spring I is so arranged as that whenwound it will tend to move the Wheel in the direction of its freerotation. With this arrangement it will be seen that when thesupporting-tape G, which is wound in a direction opposite to that of thespring, is drawn out the friction drum and wheel will be locked rigidlyand rotate together; but when said tape is released the wheel movesfreely in the opposite direction. In order, now, to retard the outwardmovement or unwinding of the supporting-tape, a friction band or brake Mis passed around the friction-drum and one end made fast to the frame A,said band or brake being essentially the same as that described in mypatent, No. 375,252, dated December 28, 1887, save that, for the sake ofconvenience, the shorter arm is toward the rear, and the head of thescrew for tightening the band is in convenient position for manipulationthrough the opening in the front of the frame, thus enabling all wear onthe band and drum to be readily taken up and the devices to be easilyand quickly adjusted for the support of light or heavy sashes.

As will be readily understood from the foregoing, the frame andoperative parts of the device are mounted in the window-casing, at thetop of the sash, and the end of the supporting-tape fastened to thebottom of the sash. Thus when the sash is moved upward the tape isslackened and the spring immediately rewinds the same; but when the sashis moved downward it has to overcome the resistance of thefriction-brake and spring, the former being adjusted to hold the sash atany desired point.

The supporting-tape is in tl e device herein shown formed of metallicribbon of any suit able kind, although it is obvious that any preferredform of tape, cord, or chain may be employed.

WVhile it is obvious that a spring of such strength as to in a measurecounterbalance the weight of the sash and tend to raise the same, andthus overcome the dead weight of the sash to a greater or less extent,may be employed, I prefer to employ a comparatively light spring, ofsufticient strength only to return the tape to position on its wheel, asthe spring may thus be made much longer and the device adapted forapplication to tall sashes, which is not practicable where the spring isrelied upon to hold the sash at a given point, owing to the greatvariation in the strength of the spring, unless the same be extremelylarge and strong. 5

Having thusdescribed my invention, what I claim as new is- 1. In asash-holder, the combination, with the frame, the axle journaledtherein, the friction-drum and supporting tape-wheel mounted on saidaxle, and the spring connected to said wheel, of the clutch-connectionbetween the drum and wheel, and the frictionbrake surrounding the drum,substantially as described. I

2. In a sash-holder, the combination, with the frame having the openingin the front, the axle jou rnaled in said frame, the friction-drummounted on said axle, the supporting tapewheel also mounted on saidaxle, the spring connected to said wheel, and the pawl-andratchetconnection between the wheel and drum, of the friction-brake surroundingthe drum, connected at one end to the frame, and the screw fortightening said brake projecting through the opening in the front; ofthe frame, substantially as described. a

3. In a sash-holder, the combination, with the frame, the axlejournaledtherein, the friction-drum mounted on the axle, and thefriction-brake surrounding said drum, of the supporting tape-wheelmounted on the axle, with the annular projection at one side surroundingthe axle, the spring connected at one end to said projection and at theopposite end to the frame, and the pawl-andratchet connection betweensaid drum and wheel, substantially as described.

JACOB BAS IAN.
